Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
According to an aspect of the present invention, an embodiment of the present invention provides a method for mounting a volume on a bare metal server, as shown in fig. 1, which may include the steps of:
s1, responding to the mounting request, and determining the identifier of the bare metal server to be mounted and the identifier of the volume to be mounted according to the mounting request;
s2, acquiring a plurality of network card identifiers corresponding to the bare metal server to be mounted according to the identifier of the bare metal server to be mounted;
s3, sending the identifiers of the volumes and the identifiers of the network cards to a storage device to bind the volumes to be mounted and the network cards;
s4, responding to the successful binding of the volume to be mounted and the network cards, and sending an instruction to the proxy service of the bare metal server to be mounted so that the proxy service finds the volume to be mounted.
According to the scheme provided by the invention, when the bare metal cloud physical machine mounts the volume, the volume can be mounted through a universal network card and service without additional hardware.
In some embodiments, the method further comprises:
acquiring identifiers of a plurality of network cards under a preset path through IPA service in an inspection mirror image of the bare metal server to be mounted;
and associating the identifier of the dry network card with the identifier of the bare metal server to be mounted, and reporting to an Ironic service so as to store the corresponding relation between the identifier of the dry network card and the identifier of the bare metal server to be mounted in a database.
Specifically, as shown in fig. 2, an fc-collector and an fc-hardware-manager may be added to the IPA service of the inspection image of the bare metal server. After the bare metal server is electrified by checking the mirror image, IPA loads an fc-collector module and finally calls an fc-hardware-manager to acquire the information of the identifier (wwpn) of the network card of the bare metal server and the identifier (wwnn) of the bare metal server. The main realization can obtain the wnnn of the current bare metal server and the wpn of all network cards through 'systol-c fc _ host-v'. After all wnns and wppns are collected, the IPA reports the collected information to the ironic service. The method can be processed by adding a processing hook in an ironic service module, wherein the hook mainly processes wwwn and wwwn information reported by IPA, and the wwwn and wwwn information can be written into an ironic database by calling an ironic client api.
In some embodiments, obtaining, according to an identifier of a bare metal server to be mounted, a plurality of network card identifiers corresponding to the bare metal server to be mounted further includes:
and calling an API (application program interface) of the Ironic service by utilizing Nova service to acquire a plurality of network card identifiers corresponding to the bare metal server to be mounted in the database according to the identifier of the bare metal server to be mounted.
In some embodiments, sending the identifier of the volume and the plurality of network card identifiers to a storage device to bind the volume to be mounted and the plurality of network cards, further comprises:
and sending the identifier of the volume and the identifiers of the network cards to a shader service by using Nova service so as to call an API (application programming interface) of the storage device to bind the volume and the network cards by using the shader service.
Specifically, when the volume needs to be mounted on the bare metal cloud server, the user can create a cloud hard disk on the cloud platform. Before the cloud hard disk is created, the type of the created cloud hard disk can be selected, for example, the type of an FCSAN cloud hard disk is created, backend storage of the type can be an FCSAN storage network, and the volume _ type of the cloud hard disk needs to be specified as FCSAN when the cloud hard disk is created. As shown in fig. 2, after initiating an attach binding operation, the user may call a Nova-computer-ironic interface, and the Nova-computer-ironic interface may call an api interface of an ironic service to obtain WWPNs of all network cards under the current bare metal server. Nova-computer-ironic will then issue the retrieved WWPN to the shader together with the identifier (uuid) of the created volume.
In some embodiments, in response to that the volume to be mounted and the network cards are successfully bound, sending an instruction to a proxy service of the bare metal server to be mounted, so that the proxy service discovers the volume to be mounted, further comprising:
and responding to the binding of the volume and a plurality of network cards, feeding back to the Nova service, calling an Ironic service, and sending an instruction to the proxy service of the bare metal server to be mounted to discover the volume.
In some embodiments, further comprising:
in response to the proxy service receiving the instruction, starting a controller to periodically scan a preset path to find the volume to be mounted.
Specifically, as shown in fig. 2, after receiving the WWPN and the identifier (uuid) of the created volume, the circle calls an API interface of the fcsan storage network to perform initialization linking, so as to bind the volume corresponding to the uuid and the network card corresponding to the WWPN. After the binding is completed, the successful binding is fed back to Nova-computer-ironic so that the Nova-computer-ironic calls an ironic driver which notifies a proxy service (input-bm-agent) to discover the volume. A firm _ CHANNEL type connector can be added to the input-bm-agent. After the instruction sent by the nova-computer-ironic is received by the Inspur-bm-agent, the controller of the FIBRE _ CHANNEL type is called to mount the volume. The Connector will periodically scan/sys/device _ path of the corresponding path until the device is discovered.
In some embodiments, further comprising:
establishing connection of a cloud platform, a bare metal server and a storage device to receive the mount request through the cloud platform.
As shown in fig. 3, the bare metal server can be accessed to the fiber switch through the fiber access of the HBA card, and then to the FCSAN storage network, so as to ensure the physical links to be communicated. The bare metal server can be communicated with the cloud management platform through a management network, so that the input-bm-agent can be communicated with the cloud management platform control node and receives and issues information of the cloud management platform control node.
According to the scheme provided by the invention, the bare metal server is accessed to the FCSAN optical fiber storage network through a network card (such as HBA). In the bare metal inspection flow, after the inspection mirror image is loaded and powered on, the IPA service in the inspection mirror image goes to a specific path to obtain the WWPN of the current bare metal server HBA, associates the obtained WWPN with the WWNN of the Ironic Node of the bare metal server and reports the WWPN and the WWNN to the Ironic through the rpc protocol. The Ironic writes the WWNN-WWPN correspondence to its own database. After the bare metal server deploys and finishes user mirroring, if a user initiates an operation of binding an fcsan type cloud hard disk to a bare metal cloud physical machine, the nova accesses the Ironic to obtain WWPNs of all HBAs under an Ironic Node to be bound, transmits all WWPNs under the Ironic Node to the finder, and the finder performs mapping of the WWPNs and the mount volume on the storage back end in an abutting joint mode. Then nova-computer-ironic informs an input-bm-agent service in the user image to discover the cloud hard disk through an ironic driver. According to the scheme provided by the invention, when the bare metal cloud physical machine mounts the volume, the volume can be mounted through a universal network card and service without additional hardware.
